Isitshalo sephethinikuyisitshalo sephethini esikhulu esisebenziswe kakhulu, okwenza ukuthi izindlela zezitshalo sephethini zibuyele kusitshalo sephethini ngesikhathi sokwenza umsebenzi wokuphendula, njengokuthi ngokusebenzisa umthetho wokuphendula wezitshalo sephethini, isikhomba sehydrophobic seSilane sizokhomba ngokwakhiwa nesikhomba sehydroxyl kwezandla zokuphendula kwezitshalo sephethini, ngakho-ke isikhomba sehydrophobic seSilane sizokhomba ngaphandle kwezandla zokuphendula kwezitshalo sephethini.
Kwesinye isikhathi sokuphendula kwezitshalo sephethini noma kusinye isikhathi sokuphendula kwezitshalo sephethini, isikhomba sehydrophobic seSilane sizokhomba ngokwakhiwa nesikhomba sehydroxyl kwezandla zokuphendula kwezitshalo sephethini, ngakho-ke isikhomba sehydrophobic seSilane sizokhomba ngaphandle kwezandla zokuphendula kwezitshalo sephethini.
Isimo somzimba
- Ithimba lisho ngokuphendula kakhulu, lisho ngokuphendula kakhulu kusitshalo sephethini esikhulu.
- Likhona ithimba elikhulu lezithimba, okwenza ukuthi libe nezindawo ezikhulu zezithimba. Kodwa, ngenxa yezandla zokuphendula, kuyisikhombisa izimo ezithile uma kuyakwaziwa ngamanzi njengesitshalo sephethini esikhulu, futhi kuzokhombisa isimo sehydrophobic esikhombisa isimo se "isimo se-lotus leaf".
Isimo somthombo
- Ukukhula kwezinye izinto kungakwazi ukusebenza kahle, kungakwazi ukusebenza kahle kusikhombisa kakhulu.
- Izinhlobo zezandla zokuphendula zizokhombisa ukuthi kuyisikhombisa esikhomba kahle kumithombo yezinto zokuphendula eziningi, futhi kuyisikhombisa esikhomba kahle kumamanzi.
Isikhathi sokusebenza
- Isitshalo sephethini: kungase kuthuthukisele kakhulu ukusebenzisa isitshalo sephethini, ukuphendula kwezinye izinto ezisebenzisa izitshalo sephethini njengemikhomba yamanzi, izitshalo sephethini zingathola ukuthi amanzi akuphumelelanga ekupheleni kwezitshalo, ngakho-ke kuthuthukisa ubudlelwane bokusebenza kwezitshalo futhi kwenza ukusebenza kwezitshalo kube kungcono.
- Isitshalo sephethini: Ezinye izitshalo sephethini, njengomaskara wezamanzi, umphoqo wezamanzi wokuphendula kanye nezinye izinto ezisebenzisa izitshalo sephethini, izitshalo sephethini zingathola ukuthi izitshalo sephethini aziphiliswe noma azoshintshwa ngamanzi, ukuze kusizele ukusebenza kwezitshalo.
- Izinto zokusebenza zokugcina: Zisebenziswe kumithombo yokugcina yezinto zokusebenza zokugcina ukuze kungasizele ukuthi amanzi akuphumelelanga ukudinwa kwezinto zokusebenza zokugcina, futhi ukusebenza kwezitshalo kungasizele ukuthi kwenziwe kahle.
Ezinye izitshalo sephethini ezisebenziswe kakhulu kumodifikeshini wezitshalo sephethini, kuzo kubalulekile:
Isitshalo sephethini esikhulu
1. Isitshalo sephethini seSilane
- Uhlobo nokwakhiwa: Lolu luluhlelo lusebenziswe kakhulu. Njengomethili trimethoksi-silane, umethili trimethoksi-silane, njengoba umfanekiso wakhe wemolekuli kumele ube nezikhomba ezisebenza ngokwakhiwa okwenzeka ngegama lokusebenza elingatholakali ngezandla zokuphendula kwezitshalo sephethini (njengokuthi umethoksi) futhi izinhlobo zezindawo zezwekazi (njengokuthi umethili futhi umfanekiso).
- Umthetho wokusebenza: Isikhomba esisebenziswe kumethili yokuphendula kwezitshalo sephethini sizokhomba ngokwakhiwa nesikhomba sehydroxyl kwezandla zokuphendula kwezitshalo sephethini ukuze kuthole isikhomba sekhimi, futhi isikhomba sehydrophobic kwezinye izinsuku sizokhomba ngaphandle, ngakho-ke kuthiwa kwenza ukuthi izandla zokuphendula kwezitshalo sephethini zibe ngaphandle kwezandla zokuphendula kwezitshalo sephethini.
2. Isilikhonzi seSilicone
- Uhlobo nokwakhiwa: njengokuthi isilikhonzi seSilicone seDimethyl, njengoba isilikhonzi seSilicone sisebenza kahle kwezinye izimo zezitshalo sephethini, kungakwazi ukusebenza kahle kwezinye izimo zezitshalo sephethini.
- Umthetho wokusebenza: Isilikhonzi seSilicone kungakwazi ukukhomba ngokwakhiwa kwezandla zokuphendula kwezitshalo sephethini noma ngokwakhiwa kwezandla zokuphendula kwezitshalo sephethini. Ngaphandle kwezandla zokuphendula, ngenxa yezandla zokuphendula zesilikhonzi seSilicone, kuzokhombisa isimo sehydrophobic esikhombisa isimo seSilicone seSilicone, ngakho-ke kuzokhomba ukuthi kuyisikhombisa esikhomba kahle kumithombo yezandla zokuphendula.
